无法重新加载 Maven 项目：无法重新连接。 java.lang.RuntimeException: 无法重新连接
Unable to reload Maven project: Cannot reconnect. java.lang.RuntimeException: Cannot reconnect
我得到了一本新的 Mac 书并安装了 IntellJ，当我尝试导入（来自现有源的新项目）一个 Maven 项目时，我得到了错误 "Unable to reload Maven project"。为了让它更简单，我刚刚通过 start.spring.io 创建了一个新的简单 maven 项目，以确保我没有任何花哨的依赖项。
我还尝试 运行 通过终端安装 mvn。这很有效！

我知道这个问题已经发布了好几次，但我已经尝试了所有建议的事情。
我确保我的主机文件只包含 127.0.0.1 本地主机。还通过
检查
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
# 255.255.255.255 broadcasthost
# ::1 localhost
也通过
检查过
ping localhost
并刷新本地主机真正转换为 127.0.0.1 的缓存
此外，我将 Maven 更新到版本 3.6.3，并将 JDK 更新到 1.8.0_251。我 运行 mvn install 通过终端完全使用这些版本的 maven 和 JDK 并且效果很好。
我还检查了防火墙，我看不到任何被阻止的调用（无论如何在终端上它正在工作）。
更多配置：
Maven 版本
maven jdk 进口商
java 版本
intelliJ 版本
在这里，我还将版本从 11.0.7 更改为 1.8。0_251（通过选择运行时插件）结果相同。

还有人知道我还能做什么吗？
非常感谢！

已知 ESET 网络保护会阻止 localhost 导致 RMI 失败并出现此错误的连接：
ution.rmi.RemoteProcessSupport - java.rmi.NotBoundException: _DEAD_HAND_
ution.rmi.RemoteProcessSupport - at sun.rmi.registry.RegistryImpl.lookup(RegistryImpl.java:227)
ution.rmi.RemoteProcessSupport - at com.intellij.execution.rmi.RemoteServer.start(RemoteServer.java:93)
ution.rmi.RemoteProcessSupport - at org.jetbrains.idea.maven.server.RemoteMavenServer36.main(RemoteMavenServer36.java:23)
ution.rmi.RemoteProcessSupport - The cook failed to start due to java.io.EOFException
禁用ESET或调整网络保护规则。联系 ESET 支持以获取更多详细信息或您需要进行的配置更改以允许 localhost 连接正常工作。
我得到了一本新的 Mac 书并安装了 IntellJ，当我尝试导入（来自现有源的新项目）一个 Maven 项目时，我得到了错误 "Unable to reload Maven project"。为了让它更简单，我刚刚通过 start.spring.io 创建了一个新的简单 maven 项目，以确保我没有任何花哨的依赖项。
我还尝试 运行 通过终端安装 mvn。这很有效！

我知道这个问题已经发布了好几次，但我已经尝试了所有建议的事情。
我确保我的主机文件只包含 127.0.0.1 本地主机。还通过
检查##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
# 255.255.255.255 broadcasthost
# ::1 localhost
也通过
检查过ping localhost
并刷新本地主机真正转换为 127.0.0.1 的缓存
此外，我将 Maven 更新到版本 3.6.3，并将 JDK 更新到 1.8.0_251。我 运行 mvn install 通过终端完全使用这些版本的 maven 和 JDK 并且效果很好。
我还检查了防火墙，我看不到任何被阻止的调用（无论如何在终端上它正在工作）。
更多配置：
Maven 版本
maven jdk 进口商
java 版本
intelliJ 版本

已知 ESET 网络保护会阻止 localhost 导致 RMI 失败并出现此错误的连接：
ution.rmi.RemoteProcessSupport - java.rmi.NotBoundException: _DEAD_HAND_
ution.rmi.RemoteProcessSupport - at sun.rmi.registry.RegistryImpl.lookup(RegistryImpl.java:227)
ution.rmi.RemoteProcessSupport - at com.intellij.execution.rmi.RemoteServer.start(RemoteServer.java:93)
ution.rmi.RemoteProcessSupport - at org.jetbrains.idea.maven.server.RemoteMavenServer36.main(RemoteMavenServer36.java:23)
ution.rmi.RemoteProcessSupport - The cook failed to start due to java.io.EOFException
禁用ESET或调整网络保护规则。联系 ESET 支持以获取更多详细信息或您需要进行的配置更改以允许 localhost 连接正常工作。
